4.Making Measurements

Testing Diodes

Caution

: To avoid possible damage to your multimeter or to the equipment under

test, disconnect the circuit power and discharge all high-voltage

capacitors before testing diodes.

(1) Rotate the rotary switch to . Press once to enter diode testing mode,

will be displayed.

(2) Connect the black test lead to the

terminal and the red test lead to the

terminal.

(3) Connect the red test lead to the positive terminal (anode) of the diode and the black

test lead to the negative terminal (cathode). The cathode of a diode is indicated with

a band.

(4) Read the diode forward bias. If the test lead connection is reversed, the multimeter

will display "OL".

Testing for Continuity

Caution

: To avoid possible damage to your multimeter or to the equipment under

test, disconnect the circuit power and discharge all high-voltage

capacitors before testing for continuity.

(1) Rotate the rotary switch to . Press twice to enter continuity testing

mode,

will be displayed.

(2) Connect the black test lead to the

terminal and the red test lead to the

terminal.

(3) Probe the test points to measure the resistance in the circuit. If the reading is below

30 Ω, the multimeter will beep continuously.

Measuring Capacitance

Caution

: To avoid possible damage to the multimeter or to the equipment under

test, disconnect circuit power and discharge all high-voltage capacitors

before measuring capacitance. Use the DC voltage function to confirm

that the capacitor is fully discharged.

Capacitance ranges are 40.00 nF, 400.0 nF, 4.000 uF, 40.00 uF, 400.0 uF, 4000 uF .
